CVE-2026-7545
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA weakness has been identified in SourceCodester Advanced School Management System 1.0. The affected element is an unknown function of the file commonController.php of the component checkEmail Endpoint. This manipulation causes sql injection. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate the vulnerable PHP fileSearch for commonController.php in the web application's source code directory. Common paths may include /include/, /controller/, or the application root.Affected if The file commonController.php exists in the application structure
-
Identify the checkEmail endpointOpen commonController.php and search for the checkEmail function or endpoint handler. Look for code that processes email-related requests.Affected if The checkEmail function/endpoint is present in commonController.php
-
Verify SQL query constructionExamine the checkEmail function code to see if user-supplied input (typically $_POST or $_GET parameters containing email data) is directly concatenated into SQL queries without using prepared statements or parameterized queries.Affected if User input related to email is used directly in SQL queries without sanitization or prepared statements
-
Confirm endpoint accessibilityDetermine if the checkEmail endpoint is accessible remotely. Check if there are any authentication requirements or if it can be reached via HTTP POST/GET requests.Affected if The checkEmail endpoint is accessible without authentication or with weak authentication
-
Test for vulnerability conditionsReview the application's configuration and PHP settings. Check if input validation functions are being used before the SQL query execution in the checkEmail endpoint.Affected if No input validation or sanitization is applied to the email parameter before SQL execution
A user is affected if SourceCodester Advanced School Management System 1.0 is deployed and the checkEmail endpoint in commonController.php directly incorporates user-supplied email input into SQL queries without prepared statements or input sanitization.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement parameterized queries or prepared statements in the checkEmail endpoint to properly sanitize user input, or apply vendor security patch if available.
